Specification of Letters Patent;

Application filed November 30, 1906.- Serial No. 345.712.

`latented March 5, 1907.

.To all whom tina/y concern.:

"Be it known that I, FRANCIS PETELER, of

l Minneapolis, Hennepin county, Minnesota,

have invented certain new and useful Im'- provements in Dumping-Cars, of which tlief ollowing is a specification.

' My invention relates to portable dumpingcars; and the obj ect of the invention is to siinplify and improve the form of bolster that takes the place of the side chains in my patent of August 5, 1902, No. 706,254, and particularly to improve the means for operating this bolster and reduce the cost of manufacturing andapplying the same.

-The invention consists generally in vario'usconstructionsl and combinations, all as hereinafter described, and ed out in the claims. v

In the accompanying drawings, forming part ofthis specification., Figure 1 is a side elevation of a dumping-car embodying my invention. Fig. 2 is an end view of the same.

particularly point- F ig. 3 is asimilar view, showing the car-body in its dumping.'` position. Fig. 4 is a detail view of themechanism for operating the swinging bolster.

In the drawing, 2: represents lthe truckframe, having a car-'body supported thereon by means of the eccentric bearings shown and described in Letters Patent of they United States,'issued to me August 28, 1906, No.v

829,667. This car-body is provided with doors 4 oneach side, operated by means of levers 5, pivoted at 6 on cross-bars 7, connecting the 'u per ends of upright standards 8, that are sec red tothe truck-frame at each end of the car. This manner of supporting and operating the doors forms the subjectmatter of a endin application for patent filed by me eptem er 29, 1906, Serial'No. 336,775.

In place of the chains usually used for preventing premature tilting of the carbody toward either side I provide bolster devices, one on each side of the car, and will now proceed to describe one of them in detail in connection with its operating mechanism, it being understood that the other bolster is sub- `stantially the same and is operated in a similar manner.

Referring to Fig. 1, 9 represents bars, preferably of metal, pivoted at 10 to the truckframe andA having laterally-turned upper ends Whereon antifriction-wheels 11. are..

mounted in position to engage the under side of the car-body when the bars are swung to a vertical position and prevent prematuretiltingof saidbody. I prefer to employ the bars from an operative to an inoperative position, or vice versa, I provide a rock-shaft 14, pivoted at 15 on the truck-frame and having itsinner end near the middle transverse line of the car and provided with a crank 16, having a forked end that is pivotallyconnected with the middle portion of the cross-piece 12 by a link 17. A longer crank 18 is provided at the other end Aof the shaft extending oppositely from the crank 16 and pivotally connected to an o erating-rod 19, having a handle 20 and slidable in aguide 21 on'a crossbar 22, that connects the upright standards 8. For the purpose of locking this operatingrod and the rock-shaft against premature movement I provide an offset 23 in said rod, into which the lower portion of the guide 21 .them at `their pivotal point. To swing' the is adapted to slip and positively hold the rod and shaft against premature movement. (See Fig. 2.) vIn this position the crank 16 will be swung to a substantially horizontal position and the link 17 will be in'line with it stantially verticalposition, where it will prevent the car-body from tilting toward that side. The handle portion 20 will project beyond the said st-andards 8, where it can be conveniently'V reached by the operator. When it is desired to dum the load, the operating# rod 19 will be lifted) in 4its guide and moved. lengthwise, vwhereupon the shaft 14 will be rocked, the crank 16 will be swunv downwardly and the bolster tilted inwardlyon its pivots to the position shown in Fig. 3 where 1t will allow the unobstructed tilting of the car-body and the discharge of the load. As soon as the car has been returned to its normal position the operator will grasp the handle 20 and swing the bolster back to its locking position beneath the body of the car. The olster on the other side of the car is operated in the same manner, the operating-rod being oppositely arranged at the other end of the car.

`and will lock the swinging bolster in a subof castings secured to ycrank at its inner end :it with said cross-piece, :also a crank at its outer end extending in the opposite direction from Asaid iirst-named crank, and means for rocking said shaft to operate said bolster.

of a bolster adapted to prevent prematuretilting of the car-body, said bolster com rising metal bars pivoted at. their lower en son the truck-frame, and antifriction-wheels mounted on the upper ends of said bars and adaptedto engage the under side of the car- .body,la cross-piece connecting said bars and longitudinally-movable means at each end of the c 'r for swinging said barsand cross-piece. to an upright position or to an inoperative.

inclined position.

3. The combination, with a dumping-car, the truck-frame, bars pivoted on saidcastings, and having straps '13, antifriction-wheels mountedv on the upper ends of said bars and adapted to engage the under side of the car-body, a cross-piece 12 connecting said bars, and means for swinging said bars to an upright operative position or to an inclinedinoperative position.

4. The combination, with 'a truck-frame, of a. swinging bolster mounted thereon, a

rock-shaft pivoted on 'said frame parallelsubstantially with said bolster and extending from a point near the middle of'said bolster tothe end of-said frame, said shaft having a and .a link 'connecting and said shaft having '5. The combination, offa swinging bolster mounted'thereorr and adapted to prevent premature tilting of the car-body, a rock-shaft having a crank'at one 'end pivotally connected with saidpbolster, and a second crank at its other end, an opercranks, means pivotally connecting with dumping-car,

atin -rod pivotally connected to saidl second cran and having an offset, and a guide wherein said rod is slidable and adapted to entersaid offset and lock said rod against longitudinal movement.

6. The combination, with a truck-frame and'adumping-car mounted thereon, of a swinging bolster mounted on said frame, and arranged to prevent premature tilting of said carfstandards 8 mounted on said truckframe at the end of' the car, a cross-bar 22 connecting saidY standards, an operating-rod .19 slidable in a guide 21 on having an oiset'23 adapted to receive said guide and means operatively connecting said rod with said bolster, whereby the longitudinal movement of said rod will swing said bolster-.to 'an operative or inoperative position.

' 7. The combination, with a. dumping-car arranged-to tilt toward each side, of swinging holsters provided on the truck-frame on each e car and arranged to prevent pre-- side of t mature'y tilting of the 'car-body, rock-shafts mountedl on said truck-frame and having said cranks on each shaft to the bo sters respectively, and operating-rods pivotally connected with the other vcranks respectively, and whereby 'said shafts will be rocked and said `holsters swung to an operative or inoperative position.

y8. `The combination, with a dumping-car, ofa swinging bolster mounted thereon and adapted to prevent premature tilting of the car, an operating-rod provided at one endof the car and having an odset, a guide wherein said rod is yslidable and 'adapted to enter said offset to lock said rod against longitudinal movement, and a rock-shaft operatively connected with said rod and bolster.
